The set command sets the requested Paging Time Window (PTW) parameters. The command configuration is
stored to Non-volatile Memory (NVM) approximately every 48 hours and when the modem is
set to minimum functionality mode with the +CFUN=0
command.
When eDRX parameters are changed using the +CEDRXS command, the PTW value is set as default. The default values can vary between different modem firmware releases. If the application needs to use a certain value, it must be set. If other than the default PTW has to be used, the %XPTW command shall be sent after the +CEDRXS command.
Syntax:
%XPTW=<AcT-type>[,<Requested_ptw_value>]
